AR-15 pistol.

Well, it's to be an AR-something. I got the stripped lower via registered FFL in Muncie, but did not notice whether the new form listed it as pistol or rifle. I bought a lower-parts-kit and upper here on INGO. So what I really want to do is to reserve the barrel from the buy on this site, and build up a true pistol with the stripped lower I bave bought.. I haven't begun a search for parts for this, because my thread and INGunGuy's thread are teaching me so much. But is this true: my registered stripped lower has never seen a spring or ANYTHING to make it a 'gun'; so if I build it as a pistol, 100%, would it need engraved per NFA regs, or is it good-to-go as built -- a pistol from the ground up? Does my 4473 NEED to say 'pistol', or 'rifle'? Thanks for laying your brains out for me to view! Pat.

depending on who you ask I personally want to make sure I have my A** covered !
was it transferred on the 4473 as long gun, pistol or rec ?
do you have a copy to prove it if necessary ?
IMO some of the old rec transferred on the old 4473's before they had the rec option are iffy if they were transferred as rifle you would have to prove otherwise or you would have an illegal SBR IF they wanted to push the issue I've been getting a copy of the 4473's for proof someday !
